Question : How to solve SQLSTATE[HY000]: General Error: 1835 Malformed communication packet on Laravel ?

Answer : All Of My Laravel Apps Running on PHP Version 7.2 and this all Project have this Error, But Those Running PHP 7.3 They have not this error so I am Just Updated my all project to PHP version 7.3

Here Is All Possible Solution For SQLSTATE[HY000]: General error: 1835 Malformed communication packet on LARAVEL.

1. Upgrade your PHP to 7.3: It appears these errors are shown on sites using php < 7.3. So upgrading your site’s PHP to version 7.3 or 7.4 should resolve the issue.

2. Downgrade MariaDB: This is a temporary fix since downgrading MariaDB will set it back to the previous state.

3. Add ‘options’ => [PDO::ATTR_EMULATE_PREPARES => true] to Database Config(config/database.php):

'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', '**'),
            'username' => env('DB_USERNAME', '**'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
            **'options'   => [PDO::ATTR_EMULATE_PREPARES => true]**
        ],

This has been suggested in some answers which might solve 1 issue but open up a lot of other issues.

4. Wait for MariaDB Update: The next update should address this issue.

5. Change PHP Version : All my Laravel apps running PHP 7.2 had this error but those running on PHP 7.3 did not. So I changed the PHP version to 7.3 and the problem was fixed. (Running Laravel 7).
